then buy a Corvette rather than bastardise a Cerbera.
I didn't - I wanted everything else to work too so used an RX7
t.I know several specialists and can read ads - many of which have had HUGE bills and rebuilds and many are sold requiring engines.
The only thing less reliable is a Speed 6 !

I think the LS7 is overpriced and a bit weedy these days. An LSX454 makes 620HP whilst the supercharged LSA and LS9 variants will make 700HP without breaking a sweat. The killer is the LSX376 which is built for boost and with a pair of turbos is good for 1000HP or more. Yours as a crate engine for £6k.
This. LSA with only intake and cam mods, no exhaust side mods, make 760 BHP after only 1k miles on the clock (Sarge 4x4 got his done by Walky UK), looking good for 800 plus once the new headers and exhaust are released.

Cold air induction
Supercharger drive pulley
Overdriven balancer pulley
Hi – flow injectors
160 degree thermostat
ECU Remap
Cam & double valve springs
Still not much to get it up to 760, and as stated running on stock headers and exhaust still.
They put an Supercharged LS3 in a Jensen Interceptor, maybe upgrade to LS7?

I absolutely loved my LS1 RX7, it was built by Craig at Dynotorque and I'd highly recommend talking to him about what ever you decide to do.
If I was to do it all again, and I probably will at some point in the future, I'd have an LS powered Porsche 968.
Plenty info on the 944/968 chassis conversion here. www.renegadehybrids.com

That's an incredibility dangerous website. I now cannot get the idea of buying a IMS failure 996 911 and jamming a LS back there.Almost makes me glad that LS Series aren't ten a penny in this country. Actually, it doesn't. Anyone got a spare green card?
Actually, while we are on the subject, how comes LS swaps always end up being so damn expensive? The figures I see from people doing the swaps always seem to be way more than the price of the engine, kit and a week or so's worth of labour to get it all fitted.

Generally the kits are only the main components to get it in you still have to buy lots of little bits and they mount up.The figures I see from people doing the swaps always seem to be way more than the price of the engine, kit and a week or so's worth of labour to get it all fitted.
Also most people tend to think whilst it's out I may as well change the clutch, upgrade the cam etc
Plus a week's work at £45+/hr adds up

In reality they aren't ten a penny here either. Motors from wreckers are without history, warranty, harness, ECU, mounts, transmission, belts, pulleys, balancers, alternators, a/c compressors, cooling systems, air box/intake etc., etc. and a scrap yard still wants $3k+ for an LS1 or 2 that could have been to the moon and back.Actually, while we are on the subject, how comes LS swaps always end up being so damn expensive?

I'm not an engineer - but these projects are never as simple as people make them out to be. Back in my foolish youth, myself and a mechanic friend (who had access to a big well equipped workshop after work hours) set about installing a 3.0L Essex V6 and 4sp trans into a 1971 Chrysler Avenger. We got there in the end, but it was a nightmarish project that threw up seemingly insurmountable challenges one after another. It really makes me laugh when I read, "I'd just bung in an LS7". The real world isn't like that.

If you see it at the lights, don't bother racing it
When looking at this type of transplant it is worth remembering that the cost of fitting an LS engine is likely to be double to treble the cost of the new engine.
Stuff mounts up. The hose fittings on my Ultima added up to £1500 on their own. The cooling system may not be up to the job, so new radiator - probably custom.
Unless you have the funds to pay someone else then a well equipped workshop and a reasonable level of skills and the ability to solve problems are a 'must-have'.

PS. It's great fun though.

"just drop an LS1 in", is probably a hangover from the practice in the USA where the sheer scale of the country, it's car culture and the amount of vehicles on the road mean ultimately the practice will have been performed tens of thousands of times.
In the UK where the engine's and parts are more scarce, garages less familiar and a much smaller after-market scene means that it is a far more specialist and expensive undertaking than in the native land of the V8. (sorry Australia)

The US also seems to have loads of kits for doing such things. These kits then aren't so easily translated to RHD cars and exhausts quite frequently become an issue over here. Gearbox aside, there isn't much to contend with an LS3 for power vs. cost. I also think complexity should be included and having put engines with turbos into cars in which they did not belong in the past, the prospect of NA is enticing.
